\n" ); document.write( "It says \"Three years ago adams age was nine times that of judy.\"
\n" ); document.write( ":
\n" ); document.write( "Let's say 3 years ago: Judy's age = J; and Adams's age = 9J
\n" ); document.write( ":
\n" ); document.write( "what is the combined age of adam and judy when judy's age is half of adam?
\n" ); document.write( "Another words in x number of years: A's age is twice J's age:
\n" ); document.write( ":
\n" ); document.write( "Adam is twice Judy's age
\n" ); document.write( "9J + x = 2(J + x)
\n" ); document.write( "9J + x = 2J + 2x
\n" ); document.write( "9J - 2J = 2x - x
\n" ); document.write( " 7J = x
\n" ); document.write( "Try this if J's age = 1, Then x = 7 years. We know A's age is 9
\n" ); document.write( "In 7 years J = 8, A = 16, There combined ages would be 24
\n" ); document.write( ":
\n" ); document.write( "Check:
\n" ); document.write( "If J = 2 then x = 14, A = 18, in 14 years then J = 16 and A = 32, their
\n" ); document.write( "combined age of 48 is not one of the answers
\n" ); document.write( ":
\n" ); document.write( "Not a very neat solution, hope it helps \n" ); document.write( "
